An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-hjqq-29pw-96wj in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ckb (crates.io): affected from 0.33.0; fixed in 0.33.2\n- ckb (crates.io): affected from 0.33.0; fixed in 0.33.2\n- ckb (crates.io): affected from 0.34.0; fixed in 0.34.1\n- ckb (crates.io): affected from 0.34.0; fixed in 0.34.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-hjqq-29pw-96wj/ (Markdown: https://insights.sbomify.com/GHSA-hjqq-29pw-96wj/index.md)","id":"GHSA-hjqq-29pw-96wj","markdown":"https://insights.sbomify.com/GHSA-hjqq-29pw-96wj/index.md","name":"GHSA-hjqq-29pw-96wj","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nervos CKB node","requires_auth":"none","summary":"An attacker can cause a denial of service on Nervos CKB nodes by broadcasting blocks with future timestamps.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\n\nAdversary can initiate DOS attack by broadcasting two consecutive blocks with timestamps in the future. \n\n### Patches\n\nPlease upgrade to v0.34.1","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Nervos CKB node panics when processing a block which parent timestamp is too new","id":"GHSA-hjqq-29pw-96wj","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.33.2"],"introduced":["0.33.0"],"last_affected":[],"package":"ckb","purl":null,"source":"GHSA-hjqq-29pw-96wj"},{"ecosystem":"crates.io","fixed":["0.33.2"],"introduced":["0.33.0"],"last_affected":[],"package":"ckb","purl":"pkg:cargo/ckb","source":"GHSA-hjqq-29pw-96wj"},{"ecosystem":"crates.io","fixed":["0.34.1"],"introduced":["0.34.0"],"last_affected":[],"package":"ckb","purl":null,"source":"GHSA-hjqq-29pw-96wj"},{"ecosystem":"crates.io","fixed":["0.34.1"],"introduced":["0.34.0"],"last_affected":[],"package":"ckb","purl":"pkg:cargo/ckb","source":"GHSA-hjqq-29pw-96wj"}],"products":null,"published":"2024-02-02","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause a denial of service on Nervos CKB nodes by broadcasting blocks with future timestamps.","url":"https://insights.sbomify.com/GHSA-hjqq-29pw-96wj/"}
